SJPECIFICATION forming part of Letters Patent No. 235,128, datedDecember '7, 1880.

Application filed October 18, 1880. (No model.)

To all whom it may concern:

Be it known that I, STEPHEN V. 0001:, of Toledo, Lucas county, Ohio,have invented a new and useful Improvement in Ice-Elevators, of whichthe following is a specification.

The nature of this invention relates to certain new and usefulimprovements in that class of elevators employed for taking ice from theplace where it is cut, and delivering the same into the house where itis to be stored.

The invention consists in the peculiar construction and arrangement ofthe parts, as hereinafter more fully set forth, and pointed out in theclaim.

Figure leis a vertical central section, the lower end resting in thewater, while the upper end is designed to rest against the icehouse,although it is shown as supported by legs in the drawings. Fig. 2 is anenlarged perspective view of the switch-chute upon which the cakes arereceived from the elevator, and alternately shunted to differentdirections. Fig. 3 is an enlarged perspective view of the chain andbuckets thereto attached.

In the accompanying drawings, which form a part of this specification, Arepresents an elevator-frame provided with an upper floor, a, and alower floor, 1).

Upon suitable shafts journaled in the two sides of the frame are the twosprocketwheels B, over and around which runs the chain 0. Thesesprocket-wheels are polygonal in form, and upon each of the flat sides,or upon every alternate one, are the rigid spurs or studs 0, designed toembrace the single bar or link d, and strike against the ends of the twobars 0, pivoted to the ends of the single bar, (I, which form the chain0, there being alternate single and double bars forming the links.

To the double bars 0, and at suitable distances apart, are pivoted thebails m of the buckets D, as shown in Fi 3, and these may be providedwith small spurs h, if desired.

To prevent the buckets from being revolved over on their pivots as theypass around the upper sprocket-wheel in the rapid movement of the belt,and thus present the buckets in an inoperative position to seize theblocks of ice, I employ the following device to retain the buckets intheir proper position on the belt, and prevent their being swung over ontheir pivots, so that the outer end of the bucket would rest on theendless chain. A transverse bar, a, is secured to the lower ends of eachbucket, (see Fi 3,) which is encircled by a ring, 0', the latter alsoencircling a pin, 19, secured to each of the double bars 0.

By this construction each bucket is retained in its proper position forseizing the blocks of ice, and is prevented from making a half-remlutionon its pivotal points as it passes over the upper sprocket-wheel.

E is an idler wheel, suitably journaled across the frame, a littledistance above the lower sprocket-wheel, to compel the slack of thechain to approach nearer the floor 1) than it otherwise would.

Motion is given to the sprocket-wheels from any convenient power.

The lower end of the floor B terminates in a platform, 70, whichprojects below and beyond the lower sprocketwheel, and it is de signed,when in use, to be immersed in the water a sufficient depth to allow thecakes of ice to be floated into the mouth of the elevator.

In operation the chain runs down upon the upper floor, a, as indicatedby the arrow, and the bale or bucket D falls behind the cake of ice L,and in the further progress of the chain draws the cake along theplatform and 1100' b, passing underneath the idler E to the e' of thefloor b, where the ice is delivered up the chute F. This chute isprovided a tongue, G, pivoted to the floor of th Qhute at m, and is ofthe shape shown in gso that the first cake of ice 1 pass tofihe chute H,and in so doing throws t swltch over, so that the next cake is di Vertedthe other chute, K, and so on, al y,

each cake of ice turns the switch for the ceeding one.

If desired, the chutes H and K m y each be provided with a similarswitch, ea ing to two additional chutes, and so the y tern of automaticshunting may be extended I pivoted to 211 double link, transverse be!12., as far as desired. pin 12, and ring 1", substantially as descrlbed,

What I claim as my invention is and for the purposeset forth. In anice-elevator, the combination, with STEPHEN V. COOK. 5 thesprocket-wheels B and endless chain 0, Witnesses:
